7. SYSTEM OPTIONS
7.1. UNIT OPTIONS
The following is a brief description of the available options for the
:
ECM120 and ECM277
—Environmental Control Module
Environmental Control Module (ECM)
provides superior dependability and security to commercial and
industrial environments. It can operate individual fixtures, lamps, circuits, or be daisy chained for con-
trolling multiple loads (One ECM is used per switching device or circuit)/qty. The ECM is perfect for hall-
ways, classrooms, corridors, meeting rooms or individual offices.
The ECM was designed specifically for the egress emergency lighting market. It is a small module that
has many applications. The dimensions are
1.25”
x1
”
x2
”,
and comes in two voltage sensing ranges—a
100VAC which has a range of 100
-
140VAC, and a 200VAC which has a 200
-
300VAC range. This small
and powerful unit is the most versatile module for many applications in the egress emergency lighting
market.
The DSPM difference is the patented ECM which is connected to selected fixtures and/or lamps which
allows normal operating parameters to be maintained. In the event of an AC power outage, the fixtures,
lamps and/or loads connected to the ECM will continue or immediately begin operating at full
-
light output
for a maximum of 90 minutes (or other run time as required by UL924 egress codes).
NOF
—Normally OFF Circuit 120Vac or 277Vac
Normally OFF Circuit
output is an excellent option when the customization needs is to provide, in addi-
tion, power only in cases of emergency (i.e. exiting lighting or evacuation power). In the event of an AC
power outage, the fixtures, lamps and/or loads connected to the emergency circuit (s) will immediately
begin operating at full
-
light output for a maximum of 90 minutes (or other run time as required by UL924
egress codes).
NOH
—Normally OFF
“
Hold On
”
Circuit 120Vac or 277Vac
Normally OFF
“
Hold On
”
Circuit
outputs are basically the same as our Normally Off Circuit option.
Both are excellent options when the customization needs is to provide, in addition, power only in cases
of emergency (i.e. exiting lighting or evacuation power). The difference between the two is that the NOH
feature allows the emergency circuit (up to 10 minutes) to remain energized after the utility power is re-
stored. This means that in the event of an AC power outage, the fixtures, lamps and/or loads connected
to the emergency circuit (s) will immediately begin operating at full
-
light output for a maximum of 90
minutes (or other run time as required by UL924 egress codes). When utility power is restored, the
emergency circuit (s) will stay energized for up to 10 minutes (depending on user setting). At the end of
the preset time, the normally
-
off circuit (s) will shutoff.
OCB
—Output Circuit Breaker/(s)
EPO
—Emergency Power Off
Emergency Power Off
option gives the user the ability to instantly turning the UPS off without having to
throw the breakers. The EPO option is primarily used as a personnel safety feature that will shutoff all
power to the UPS output and load. When pressed the input utility power is still on the terminal block, but
the microprocessor turns the inverter and rectifier off.
RSSP
—Remote Indicator Panel
Remote Indicator Panel
option enables the user to remotely monitor the UPS. Through the use of re-
lays, the RSSP allows the user to know if the UPS is operating on the input utility power or its battery
bank and if the UPS
’
s output is
“
On
”
or
“
Off
”.
This feature allows for the UPS to be located away from
the load that it operates or controls.
SNMP
—SNMP Card
Simple Network Management Protocol
(
SNMP
) is an "Internet
-
standard protocol for managing devic-
es on IP networks.
”
Devices that typically support SNMP include routers, switches, servers, work-
stations, printers, modem racks, and more. It is used mostly in network Management systems to moni-
tor network
-
attached devices for conditions that warrant administrative attention.
UPS and Emergency Lighting Inverter manufacturers have adopted the SNMP standard to allow users
to easily communicate with their UPS systems. SNMP makes it possible for one node on a network to
communicate with another node enabling the power supply to send out emails to anyone on the net-
work, if an email server is available.
